Dave walked to the store at an average speed of 3.5 miles per hour for 0.5 hours. Then he jogged to his friend's house at an average speed of 7 miles per hour for 1.5 hours. What was the total distance in miles that Dave traveled?

21 miles

Step-by-step explanation:

s=vt

Vt = 3.5mi/h + 7mi/h

Tt = 0.5 hr + 1.5hr

= 2 hr

St = 10.5(2hr)

= 21 miles
